Four case studies are presented which illustrate the use of masonry as a structural material. Results of laboratory studies for unreinforced piers subjected to in-plane lateral forces,...
Feasibility of FRP Molded Grating-Concrete Composites for One-Way Slab Systems
This paper describes the behavior of one-way concrete slabs reinforced with Fiberglass Reinforced Plastic (FRP) molded grating. FRP molded grating is commercially available and is mainly...
Dynamic Parameters Analysis of Piles
This paper presents an analysis for the dynamic parameters of a single pile. The analysis allows consideration of pile-soil interaction, soil natural layered behavior and floating pile...
Cyclic Behavior of a Deepwater Normally Consolidated Clay
A comprehensive advanced laboratory testing program was undertaken to study the cyclic behavior of clays under various combinations of one-way and two-way cyclic loading. This work was...
Dynamic Response Characteristics of Jack-Up Drilling Units
The effects of five parameters on the dynamic amplification of the global base shear on a deep water jack-up drilling unit were analyzed using a time domain nonlinear model. The five parameters...
A Laboratory Study of Shock Waves in Frozen Soil
This work has focused on two aspects of dynamic behavior of frozen soil: first, on the shock pressure attenuation, and second, on the shock Hugoniot. The use of long bars of frozen soil...
Friction and Cohesion in Ice Rubble Reviewed
An argument is ventured that accumulations of ice rubble undergoing continuous shear deformation are essentially cohesionless. In terms of the Mohr-Coulomb failure criterion, therefore,...
A Mechanistic Approach to Pavement Design for Nome Airport
The analysis of performance and design of the pavement structure for the North-South runway at Nome Airport is based on the mechanistic approach. In the mechanistic approach, calculated...
Improved Corrosion Protection for Flue Gas Systems Utilizing a Dual Liner Concept
A unique system of corrosion resistant materials has shown excellent performance and durability in flue gas systems for fossil plants, cogeneration plants, waste incinerators and waste-to-energy...
Low-Rise Shear Wall Failure Modes
A summary of the data that are available concerning the structural response of low-rise shear walls is presented. These data will be used to address two failure modes associated with shear...
Structural Approximations in Multi-Story Buildings
Simplified computer analyses and various approximate hand calculation methods are extremely valuable in structural engineering for multi-story buildings both during the preliminary design...
Approximate Preliminary Methods for Design of Lateral Load Resisting Systems in High Rise Buildings
A new group of optimization programs uses the speed and power of modern computers to eliminate the need for guessing preliminary sizes. Starting with any arbitrary sizes and a fixed geometry,...
Multiple Event Considerations for Postclosure Seismic Hazard Evaluations at Yucca Mountain, Nevada
Postclosure waste canister design requirements suggest the values used for seismic design have less than a 10% chance of being exceeded in a 1,000 year postclosure period. Considerably...
Strain Distribution in Fault Zones and Fluid Flow
Field and laboratory studies have shown that mechanical shearing in fault zones produces a repeatable fabric that changes with increasing shear strain. In the brittle field of mechanical...
Correlation of Hydraulic Conductivity and Sonic Velocity in Water-Saturated Tuff
A laboratory study was conducted to investigate the correlation of hydraulic and sonic properties of water-saturated tuff. The hydraulic test used a new rock block testing machine, which...
Potential Uses of Lead in Nuclear Waste Disposal
In order for lead to be considered as a nuclear waste packaging material, it must be shown that it has adequate corrosion resistance, and that it does not degrade the properties of other...
Accurate Response Analysis of Seismic Distributed Mass Systems
A dynamic analysis technique of distributed mass structures is presented with a combination of the dynamic load factor approach and the dynamic stiffness matrix method. The dynamic stiffness...
An Electronic Specification for the Earthquake Resistance Design of the Highway Bridges in Pennsylvania
An interactive C program for the seismic design of highway bridges in the state of Pennsylvania is described in this paper. The program was developed in C language on a personal computer....
